Question

If an object is kept 10 cm away from a convex mirror with a radius of 5 cm curvature, then its magnification will be​

Answer 1

Answer:

0.2 magnification

Explanation:

<Check the sign conventions>

u = -10 cm

f = 2.5 cm ( f = radius of curvature / 2 )

1/f = 1/v + 1/u

1/2.5 = 1/v  - 1/10

2/5 + 1/10 = 1/v

5/10 = 1/v

v = 2 cm

magnification = -v/u

= - 2 / -10

= 1/5 or 0.2
